 ## Overview
 
-Successfully implemented the foundational structure for `@objectstack/plugin-auth` - an authentication and identity plugin for the ObjectStack ecosystem.
+Successfully integrated the Better-Auth library (v1.4.18) into `@objectstack/plugin-auth` - an authentication and identity plugin for the ObjectStack ecosystem. The plugin now has the better-auth library integrated with a working AuthManager class and lazy initialization pattern.
+
+## Latest Updates (Phase 1 & 2 Complete)
+
+### Better-Auth Integration
+- ✅ Added better-auth v1.4.18 as runtime dependency
+- ✅ Created AuthManager class wrapping better-auth
+- ✅ Implemented lazy initialization to avoid database errors
+- ✅ Added TypeScript types for all authentication methods
+- ✅ Updated plugin to use real AuthManager (not stub)
+- ✅ All 11 tests passing with no errors
+
+### Technical Improvements
+- Better-auth instance created only when needed (lazy initialization)
+- Proper TypeScript typing for HTTP request/response handlers
+- Support for configuration-based initialization
+- Extensible design for future features (OAuth, 2FA, etc.)

-- **AuthManager class** - Stub implementation with @planned annotations
+- **AuthManager class** - Real implementation with better-auth integration
+- **Lazy initialization** - Better-auth instance created only when needed
 - **Route registration** - HTTP endpoints for login, register, logout, session
 - **Service registration** - Registers 'auth' service in ObjectKernel
 - **Configuration support** - Uses AuthConfig schema from @objectstack/spec/system
+- **TypeScript types** - Proper typing for IHttpRequest and IHttpResponse

 ## Key Design Decisions
 
-1. **Stub Implementation**: Created working plugin structure with @planned annotations for future features
-2. **better-auth as Peer Dependency**: Made better-auth optional peer dependency to avoid tight coupling
-3. **IHttpServer Integration**: Routes registered through ObjectStack's IHttpServer interface
-4. **Configuration Protocol**: Uses existing AuthConfig schema from spec package
-5. **Plugin Pattern**: Follows established ObjectStack plugin conventions
+1. **Better-Auth Integration**: Integrated better-auth v1.4.18 as the core authentication library
+2. **Lazy Initialization**: AuthManager creates better-auth instance only when needed to avoid database initialization errors
+3. **Flexible Configuration**: Supports custom better-auth instances or automatic creation from config
+4. **IHttpServer Integration**: Routes registered through ObjectStack's IHttpServer interface
+5. **Configuration Protocol**: Uses existing AuthConfig schema from spec package
+6. **Plugin Pattern**: Follows established ObjectStack plugin conventions
+7. **TypeScript-First**: Full type safety with proper interface definitions
